Mountain lions don’t drink alcohol as a rule—for that spectacle we have chimpanzees, cows, and crows, always with some enabling human nearby—but that didn’t keep one curious young puma from wandering down from the foothills of the Sierra Nevada into Harrah’s Casino in Reno, Nevada. The cat, bewildered by the revolving door, took shelter under an outdoor stage, where it was tranquilized and taken back up into the mountains. Said a Nevada Department of Wildlife spokesperson who helped bag the cougar, the incident “was almost the equivalent of being a stupid teenager.” Most stupid teenagers, of course, aren’t driven from their homes by territorial adults, though plenty are. That’s likely just what happened to our young Puma concolor, for whom we’ll wish happier times up in the hills.

Our enterprising mountain lion could always head to Chicagoland, where, for the third time in the last decade, a mountain lion was spotted heading toward the bright lights of Michigan Avenue. It wasn’t far: according to a well-done article in the Chicago Reader, it was seen hopping a fence just about a mile west of the Lincoln Park Zoo. Regrettably, and controversially, and wrongly, Chicago police shot the cougar dead.

If the mountain lion had been a giraffe—now there’s a thought experiment—and the giraffe’s mother had been around to witness the shooting, she would have grieved. Yes, grieved. So conclude zoologists who witnessed grieving behavior on the part of a mother giraffe in the face of the death of one of her young. Writes researcher Fred Bercovitch in the African Journal of Ecology, “The evolutionary basis for species’ reactions to dead conspecifics remains elusive, but assessing the cognitive and social foundations for animal reactions is contingent upon compiling records from multiple species.” Before you respond with the mostly annoying but sometimes useful phrase “You think?,” it’s worth parsing this: most observations of grieving behavior involve chimpanzees and elephants, which are considered to be “intelligent” animals. Giraffes generally are not, but the fact that three mothers have shown sorrow at the loss of their young attests otherwise—and at the lack of understanding on the part of humans who assign IQ scores in the first place.

There are still giraffes left in this world, for now. And there are still elephants, and crows, and chimps. But what of tigers, fast dwindling, and dodos and mastodons, long gone? Argues futurist and tech guru Steward Brand in passing in a recent interview in Wired, it’s increasingly possible to take the DNA of extinct species and produce the animals anew, returning them to the wild. The question remains: What wild? Still, Brand’s note is an optimistic one for people who aren’t afraid of the thought of free-roaming cats and other critters; says Brand, “I want them to know that de-extinction is coming.”

"Service Animal" Scammers (New Yorker): An increasing number of your neighbors have been keeping company with their pets in human-only establishments simply by claiming that the creatures are their licensed companion animals and are necessary to their mental well-being.
